PILE PERFORMANCE EVALUATION METHOD
PROBLEM TO BE SOLVED: To propose a pile performance evaluation method capable of simply evaluating performance of a pile.SOLUTION: A pile performance evaluation method includes acquisition processing S10, estimation processing S12, and evaluation processing S14. The acquisition processing S10 acquires a real displacement of a real pile head at a predetermined frequency on the basis of measured microtremors of the pile head. The estimation processing S12 estimates an estimation displacement of the pile head at the predetermined frequency on the basis of measured various elements of the ground. The evaluation processing S14 evaluates performance of a pile having the pile head on the basis of the real displacement and the estimation displacement. The estimation processing S12 includes creation processing of creating a pile/ground spring model by inputting temporary pile various elements and ground spring various elements set on the basis of the microtremors to a previously set pile/ground spring model.SELECTED DRAWING: Figure 2
【課題】 簡易に杭の性能を評価することができる杭の性能評価方法を提案する。【解決手段】 杭の性能評価方法は、取得処理Ｓ１０と、推定処理Ｓ１２と、評価処理Ｓ１４と、を含む。取得処理Ｓ１０は、測定された杭頭の常時微動に基づいて実際の杭頭の所定周波数における実際変位を取得する。推定処理Ｓ１２は、測定された地盤の諸元に基づいて杭頭の所定周波数における推定変位を推定する。評価処理Ｓ１４は、実際変位と推定変位とに基づいて杭頭を有する杭の性能の評価を行う。推定処理Ｓ１２は、予め設定された杭・地盤ばねモデルに、仮の杭諸元と、常時微動に基づいて設定された地盤ばね諸元と、を入力して杭・地盤ばねモデルを作成する作成処理を含む。【選択図】図２
